at 60 L0osd'rechtscheweg Hilver- Netherlands, have invented: certain fo'rthe Manufacture of PliantFloor-Qovering; of which :the' following; is a spec'ifica- 'tion.

I I It is Well-known that hitherto for the cov- This'invention relates to a-process for the manufacture of a pliant floor coverings-.1,

' 'eri ng of floors the so called linoleum is gen-' erally used which is a compositionma'de out of a mixture-of linseed oil contingently it partly' oxidized, with I as Wood :fiou'r and 1 cork powder,

As the linseed oil oxidizes when exposed to the air the at'first Wet, plastic material* I obtains the dryness and solidity required for 7 I which may'b'e' rollediupa that has- -fa length its use as a flooncovering.

' Owing to this fact the I storing of large quantities of linoleum is "necessary sothat the cost prlce of the article is considerably Moreover it Iis necessairy to apply "first I the plastic-mass isbut I little coherent the stickiness of the 1 mass be ng diminished by addingja' large] lay and chalk, The application of saidlayer makes the, linoleum a very costly product especially as the jute, prices.

:the mass agentit is possible to make a floorcovering 1 without a backing. T

, The. economical advantages 'of .thisI'are quite obvious. I As the glue dries quickly the product may bej'u'sed a few day'safter, it hasf'been pre pared. Soin 'the Works-which produce the floor covering" according to the invention a commercialproduct is obtained which may be -transporte'd immediately,-

Finally the mass is mixed with 640 grams of china-clay, lenswhite, magnesia or another filling material containing little or no I lime. .By mixing'the above substances chinery a homogeneous mass is obtained 7 which is then. rolled to sheets of the required thickness. n

As no use is made of jute or another fabric;it is desirable tostrengthen the mass during the treatment. This may be attained :'by-applying a piece of fabric of the required dimensions on which the mass "is spread out and'passed together through the rollers. When the sheetsare ready, they are put into a drying room in tain the properties required.

To make the material insoluble in water and to obtain the required hardening, after some days the sheets may be spread over 1 with. formalin, while the fabric which has served as a support may be removed after some days. .The pliant floor covering ob- V .ing the-lack of a fabric or even of'a fibrous 'materialan extraordinary resistance whlch tained in this way possesses'notwithstandust be ascribed {t the g ness of the pplied glue.

1'. In a process for preparing a pliantfloor covering comprising a filling material glue solutionprevious to the mixing with the heavy glue, in connection. with the step of adding nitric acid to, the binding mass and incorporating the mass with the heavy glue. after the latter has been treated with nitric} acid. i

3. In a process for preparing: a pliant floor covering composed ofa fillingmaterial and a binding mass, including asolution of dilute glue and a heavy glue, the step of saturating the filling material with a quantity of the dilute glue solutiom mixingthe 7 0 material with the binding mass and coagulating an additional quantity of glue solution. A. A pliant floor covering containing the reaction products of glue, glycerin, a coagulating agent, nitric acid and wood flour.

5. A pllant floor coverlng containing the reactlon products of glue, glycerin, acoagulating agent, nitric acid and wood flour and \i a filling material. 80, 6. I pliant floor covering containing the reaction products of about 110. parts of glue, 60 parts of glycerin, a coagulating agent, 15 parts of nitric acid and parts of wood flour, and a-filling material.

Y In testimony whereof I aflix my signature.
